Inclusion criteria

Patients who have signed informed consent form before initiation of any study related procedure.

General good health (except the COPD diagnosis) and free of any concomitant conditions or treatment that could interfere with study conduct.
An established physician diagnosis of COPD (GOLD 2022).
Post-bronchodilator FEV1≤80% and ≥40% of predicted normal values (GLI-2012), and post-bronchodilator FEV1/FVC ratio ≤0.70.
Predose FEV1 values at Visits 4 and 5 within ± 20% of the Visit 3 FEV1.
Able to replace their current short-acting bronchodilators with study-provided albuterol/salbutamol inhalation aerosol provided at the Screening Visit (Visit 1) for use as needed for the duration of the study.
Patients must be able to discontinue their COPD maintenance medications during the run-in and treatment periods.
Patients must be able to withhold their short-acting β2-agonists for at least 6 hours prior to spirometry on each clinic visit at the discretion of the investigator.
Current or ex-smokers with ≥10 pack-year smoking history (Note: Pack-Year= (cigarettes smoked per day x years smoked)/20)).
Not pregnant , breastfeeding, not a woman of childbearing potential (WOCBP) or WOCBP using an acceptable contraceptive
No occurrence of an upper or lower respiratory tract infection during the run-in period.
No COPD exacerbation, defined as any worsening of COPD requiring an emergency department visit or hospitalization, or requiring excessive use of the albuterol/salbutamol rescue medication during the run-in and/or treatment period at the discretion of the Investigator, or the use of antibiotics and/or corticosteroids during the run-in period and/or treatment period.

Exclusion criteria

Treatment for COPD exacerbation within 12 weeks prior to the Screening Visit or 2 or more exacerbations in the last year.
Hospitalization for COPD or pneumonia within 12 weeks prior to the Screening Visit.
History of a life-threatening COPD episode that required intubation and/or was associated with hypercapnia, respiratory arrest, hypoxic seizures, or mMRC (Modified Medical Research Council) dyspnea Grade 4.
Acute upper or lower respiratory tract infection, sinusitis, rhinitis, pharyngitis, urinary tract infection or illness within 8 weeks prior to the Screening Visit.
Use of immediate-release (Oral or IV) corticosteroids within the last 30 days and/or extended-release corticosteroids (Depot or Local) within the last 12 weeks prior to the Screening Visit
Patients with a history of asthma or a clinical diagnosis of asthma, allergic rhinitis, or atopy; a total blood eosinophil count above 600/mm3.
Patients with an abnormal/clinically significant 12-lead electrocardiogram (ECG) prior to and during screening visit, during the run-in and treatment periods.
Patients with myocardial infarction or unstable angina in the last 12 months; unstable or life-threatening cardiac arrhythmia requiring intervention in the last 12 months; or New York Heart Association Class II-IV heart failure.
Patients with documented pulmonary hypertension or clinical signs of right heart failure (indicated by an increase in jugular venous pressure with or without peripheral edema) or patients who require chronic oxygen use for >12 hours per day.
Presence of glaucoma or a history/family history of glaucoma.
History of paradoxical bronchospasm, narrow-angle glaucoma, prostatic hyperplasia, bladder-neck obstruction, or any other condition, which, in the opinion of the Investigator, would contraindicate the use of an anticholinergic agent.
Presence or history of urinary retention.
Historical or current evidence of a clinically significant disease (Note: Significant is defined as any disease that, in the opinion of the Investigator, would put the safety of the patient at risk through participation, or which could affect the efficacy or safety analysis if the disease/condition exacerbated during the study) including, but not limited to:
Cardiovascular (e.g., congestive heart failure, uncontrolled hypertension, uncontrolled coronary artery disease, stroke, or non-controlled arrhythmias),
Hepatic, renal, hematological, neuropsychological, endocrine (e.g., uncontrolled diabetes mellitus, uncontrolled thyroid disorder, Addison's disease, and Cushing's syndrome),
Gastrointestinal (e.g., poorly-controlled peptic ulcer disease),
Pulmonary disease other than COPD (e.g., alpha-1 antitrypsin deficiency, active bronchiectasis, cystic fibrosis, broncho-pulmonary dysplasia, sarcoidosis, lung fibrosis, pulmonary edema, interstitial lung disease, lung or mediastinum proliferative process including malignancies).
Patients who have undergone thoracotomy with pulmonary resection, have plans to undergo lung transplantation or lung volume reduction therapy, or have had lung volume reduction surgery within 12 months prior to the Screening Visit.
Have any of the following conditions that, in the judgment of the Investigator, might cause participation in this study to be detrimental to the patient, including but not limited to:
Current malignancy excluding basal cell carcinoma. (Note: History of malignancy is acceptable only if the patient has been in remission for one year prior to the Screening Visit. Remission is defined as no current evidence of malignancy and no treatment for the malignancy in the 5 years prior to the Screening Visit.
